Hi all,
I am developing a filter driver for my current project, which will filter the packet and block the packets according to user choice. I want to add some more functionality like Media connect status. But I am unable to do this. If i will use this code, my internet connection is disabling.
Below is my code…
VOID
FilterStatus(
IN NDIS_HANDLE FilterModuleContext,
IN PNDIS_STATUS_INDICATION StatusIndication
)
/*++
Routine Description:
Indicate Status Handle
Arguments:
FilterModuleContext: Pointer to our filter
GeneralStatus:
StatusBuffer:
StatusBufferSize:
Return Value:
NONE
NOTE: called at <= DISPATCH_LEVEL
FILTER driver may call NdisFIndicateStatus to generate status indication to all higher layer modules.

PMS_FILTER pFilter = (PMS_FILTER)FilterModuleContext;
